Subject: How does Suse do live filesystem revert with btrfs?
Date: Sat, 3 May 2014 17:52:57 -0700	[thread overview]
Message-ID: <20140504005257.GF9061@merlins.org> (raw)

(more questions I'm asking myself while writing my talk slides)

I know Suse uses btrfs to roll back filesystem changes.

So I understand how you can take a snapshot before making a change, but
not how you revert to that snapshot without rebooting or using rsync,

How do you do a pivot-root like mountpoint swap to an older snapshot,
especially if you have filehandles opened on the current snapshot?

Is that what Suse manages, or are they doing something simpler?

Thanks,
Marc
